Security on Marvel movies is famously airtight. I once toured a Marvel set and there were signs and warnings everywhere instructing people to protect every secret they saw, to only go in areas where they were allowed, and to wear proper identification at all times. It was like a military facility or something.

Of course, if you’re one of the big stars of these movies, you can just do whatever you want.

Case in point: Check out the behind-the-scenes video Chris Pratt shared on his Instagram. It shows a large chunk of the Avengers: Endgame cast assembled on the set (really just some rubble in front of a green screen). We see Dave Bautista, Chris Evans, Sebastian Stan, Don Cheadle, Mark Ruffalo, Jeremy Renner, Paul Rudd, Robert Downey Jr., and a whole bunch of stunt doubles all hanging out and putting together the film’s final battle scene. And Sean Gunn, who plays Rocket on set in the MCU (and also plays Kraglin in the Guardians films) has a great punchline at the end of the video.

Take a look for yourself:

I just love seeing the folks in their makeup and, like, a hoodie trying not to fall asleep standing up while the intricacies of this immensely complex sequence are worked out very slowly. I also enjoy seeing how much energy Chris Evans has on set. The dude looks legitimately happy to be a part of this thing, which is fun to see.

Avengers: Endgame is in theaters now. Hopefully Chris Pratt took more illegal videos, I would like to see them.
